Glossary
If a computer wants to transfer data packets to a computer in
another network, it must first transmit the packet to the gate-
way. To do this, the computer must know the address of the
gateway.
If all packets that cannot be delivered in a local network al-
ways are to be transmitted to their given recipients via the
same gateway, for this purpose the address of the gateway
must be saved as the default gateway in the network settings
of the computer.
Such a default gateway for the computer is negotiated auto-
matically by the operating system or the dialing software
whenever an ISDN-Controller or ADSL-Controller establishes a
connection to the Internet.
If a router is used for the shared Internet access in a local net-
work, the IP address of the router must be entered as the de-
fault gateway in the TCP/IP settings of each computer that
wishes to use the Internet connection.
HSPA
short for High Speed Packet Access
HSPA is a third-generation mobile radio standard further de-
veloped from the the UMTS mobile radio standard. HSPA pro-
vides for throughput rates in the mobile radio network that
are comparable with DSL (3.6 to 13.98 Mbit/s).
hub
A hub is a device that is used to connect network devices to
each other, for instance through an Ethernet. Network devices
are connected to each other in a star network, with each net-
work device connected to the hub. There are no direct con-
nections between the network devices.
A hub can either send or receive data. Received data are sent
to all connected devices. All connected devices share the da-
ta throughput.
